Overview

CoreWeave AI Object Storage Usage-Based Billing introduces a third tier of storage pricing for AI Object Storage: Hot, Warm, and Cold. Usage-Based Billing replaces the previous Automated Archive feature, and is enabled by default starting October 31, 2025. Data billed as Cold has the same performance as Hot or Warm data. This feature is enabled by default starting October 31, 2025.
